Say If I have Enough space Remaining In The Camera's Memory Card and the Camera's Batteries are Also Nearly Full After a Day of Diving Will It Be Ok If I Dont Open the Housing for that Day and Use It the Next day ? I Mean Just Washing the Housing from Outside with Fresh Water Throughly and Using it for the next days dive

I think maintenance will depend on the type of housing you have, but you should be fine just rinsing the housing and not opening it (plastic more than aluminum).

That said, I have been out on shoots where I thought I had plenty of battery life in my strobes, only to find they ran out of juice because I had some great subjects and took more shots than planned. Also, if you ever do have a camera flood, odds are you would lose the shots on your card since they were not downloaded.

Just returned from a three week dive/photo outing, and I left sync cords attached the entire time. I cleaned port "O" rings when I change ports, and the housing's back plate "O" ring after I removed the camera and downloaded photos. This is my SOP, and it has worked well for years.

Or Do I Need to Open it Each and Everyday ?

Thankyou

I would strongly argue that it is better to take the card out, download it to your computer/whatever gizmo you use for storage. I would also change batteries before each day's diving. I know that you might think you have enough battery or card space but just when the whaleshark appears at the end of the second day your camera will have run out of power. The risk to opening and closing the housing is de minimis if you are careful but losing the pic of a lifetime to a low battery is as they say priceless.Bill

I agree, don't ever risk loosing strobe power while in the water. I recharge batteries before each day of diving and carry a spare 8.I usually take more shots if I am doing macro as opposed to WA, but almost always use a 4 GB card. Can change cards in the field as needed, but I just worry about loosing everything on say an 8 GB card. Again as noted above start with a fresh card each day, so you have protected the previous shots and also take the time to review what you shot so you can if possible redo mistakes etc.I also agree with cleaning O rings as you go. The back as you change cards (in the field I don't take the O ring out). Port O rings when you change lenses and sync cords about every 20-30 dives. Seems to work...

Besides running out of batterie or space in your card I would be concerned with your photos that are already in the card. It is not good to have it all in one place. Can you imagine after a few days of diving loosing all the pictures instead of "just" some from your last dive?I know it takes some time cleanning and all that , but you will get used to it until it is part of the routine.I guess it is obvious I do wash, open and check everything....
